Up to 6kW, Rack-Mountable, Fiber-Coupled Module

Features
The EF series combines multi-kW fiber-coupled diode laser power with a small
footprint and high efficiency. Available up to 6kW the 19-inch rack mounted
unit is designed to meet the requirements for OEM customers such as system
integrators.
This beam source provides the necessary interfaces on the rear side and is able
to couple into a 1000µm fiber 0.22NA. Typical applications are cladding,
brazing, hardening, and heat conduction welding.
